It depends on what your applications are. If you are just content with the m030 set, you need nothing else. However, you may find some dust boots ripped, worn control arm, bushings etc. While you're in there, it would be a good idea to replace some items, however I just went and replaced my struts & springs.
I used these instructions, and they are pretty good.
